time_get::do_get_weekday
A protected virtual member function that is called to parse a string as the name of the day of the week.
virtual iter_type do_get_weekday(
iter_type _First,
iter_type _Last,
ios_base& _Iosbase,
ios_base::iostate& _State,
tm* _Pt
) const;
Parameters
_First
Input iterator addressing the beginning of the sequence to be converted._Last
Input iterator addressing the end of the sequence to be converted._Iosbase
A format flag which when set indicates that the currency symbol is optional; otherwise, it is required._State
Sets the appropriate bitmask elements for the stream state according to whether the operations succeeded._Pt
A pointer to where the weekday information is to be stored.
Return Value
An input iterator addressing the first element beyond the input field.
Remarks
The virtual protected member function tries to match sequential elements beginning at _First in the sequence [_First, _Last) until it has recognized a complete, nonempty weekday input field. If successful, it converts this field to its equivalent value as the component tm::tm_wday, and stores the result in _Pt->tm_wday. It returns an iterator designating the first element beyond the weekday input field. Otherwise, the function sets ios_base::failbit in _State. It returns an iterator designating the first element beyond any prefix of a valid weekday input field. In either case, if the return value equals _Last, the function sets ios_base::eofbit in _State.
The weekday input field is a sequence that matches the longest of a set of locale-specific sequences, such as Sun, Sunday, Mon, Monday, and so on. The converted value is the number of days since Sunday.
Example
See the example for get_weekday, which calls do_get_weekday.
